This invention relates to boxes and the object of the invention is toprovide a box for heavy duty and rough handling which 1s braced so as towithstand strains from all 5 sides and angles which would break anordinary box.

Another object of the invention 1s to provide a box of steel andlaminated wood construction so tied together so that it has greatrigidity and cannot be readily crushed or broken.

A further object of the invention is to provide a box having a top andbottom steel frame containing insertible laminated wood panels, the topand bottom frames being tied together so that the combination of thepanels and the frames provides a box which will not rack or twist understrain.

A further object of the invention is to provide a box in which thedifferent parts may be replaced with a minimum of labor when worn out orwhen the panels are'broken.

These objects and the several novel features of the invention arehereinafter .more fully described and claimed and the preferred form ofconstruction by which these objects are attained is shown in theaccompanying drawings in which Fig. 1 is a perspective View of a boxembodying my invention.

Fig. 12 is a section taken on line 12'12 of Fig. 8.

' Fig. 13 is a perspective view of one of the metal box corners.

The box comprises a rectangular upper frame member 1 which is channelshaped in cross section as shown in Fig. 2 and is provided with aninternally extending horizontal flange 2. The lower rectangular frame.-7;

member 3 is of substantially the same form in cross section and isprovided with an internally extending flange 4. The side panels 5 andend panels 6 of the box are formed of laminated wood and are positionedin the channels 1 and 2 as will be'understood from Fig. 2.

The panels 5 and 6 are brought into end to end relation as shown in Fig.3 and in order to cover thls corner a sheet metal angle iron 7 ispositioned thereover and the lower channel 3 is extruded at the corner8so aslto provide space into which the angle member 7 may be positioned.A similar extrusion is formed in the upper frame member to .sup-

port the upper end'of the member 7 as will be understood from Fig. 1. Inthis way the corner member 7 is supported ateach corner of the box andprotects the corner and improves the appearance by covering the ends ofthe panels. The box is tied together at the four corners by the bolts 9shownin Figs. 1 and 4 which extend through the flanges 2 and 4 at thecorners and by turning the nuts up on the bolts .9 the top and bottomrec- 5 tangular framemay be drawn together'to apply a pressure on thepanels. These bolts secure the portions of the box together into aunitary structure andthus a box is provided which will not rack in'use.

form the compression members while'the bolts 9 at the four corners formthetension It will be noted that in this structure the panels 5 and '6members and the channels or rectangular frames in rectangular form andprevent the .have :shown the tension 1 members :9 :as bolts they may be.long; rivets which are upset at each end to place a pressure on thepanels the rivets being preferably upset sufliciently to draw the framemembers 1 and 3 together and prevent looseness.

1, An alternative arrangement for securing the'box together at thecorners consists of a wire 12 which isbentinwardly. ateach end andinserted through apertures provided therefor in the frame members 1 and3 and thei'corner members 7 and the inner ends of the wirerare bent overas: shown in Figs..5

and.i6. One or two ofthese wires may be provided at eachcorner andrthecorresponding panels are aperturedto allow the ends of "the wire .to beinserted therethrough.

1 Occasionally through misuse one of the ,panels maybe stavedin, inwhich case it is necessary to replace the panel. When this occurs, ifboltsare used, it is merely necessary to remove the nuts from the boltsand liftthe .top frame member, off the box, at which. time Ithe brokenpanel maybe removed and a new jpanel'inser'ted. 'When long rivets areusedit is necessary to cut. .the rivets and remove them, and utilize new=rivets when reassem- Tblingithe box. 1

j; "When wires are used, as shown-in Figs-5 and 6, the wires maybe cut.and replaced bv .new wires -when. the box is reassembled.

Also When-Qthe box is'taken zapart anypiece o'f the' box .which/is bent,broken or otherwise damaged maybe readily replaced-and by means .of themetal edges providedabout the. edges and cornersof the box the .boxiswellv protected and will stan'da great amount of wear and roughhandling.

As shown in'Figs. 1 an'd'2the flanges .2 and 4- 0f the frame .members 1and 3 strengthen the box by'th-e angle construction :and at the sametime a bottom may bexprovided and attached to the lower flange 4 in anydesired manner and a top may be provided. and-'attachedto the upperflange 2 if desired to provide aclosed receptacle. When the box is usedas abottlecrate'it is ileftzopen atithestop-and. bottomas shown and .awire bottle rack is positioned directly onzthe lowermetalflange 4;.

"If desiredthechannel framemembers .1

and 3 maybe provided with inturned lugs ,13, as shown in Fig. 7,which-engage the panels, and hold-"them in their respective channels-These lugs 13 are pressed ,intothe channel and ,as the 'panel is.inserted there- .the box by the laminated between the panel is grippedthereby and is held from displacement.

In Figs. 8, 9, 10, 11, 12 and 13 an alternativeform of box is shownhaving round corners. In this form the frame channel 14 at the top andbottom is provided with rounded corners and theinner flanges 2 and 4, ofthe type shown in Figs. 1 and 2, are left off to increase the size ofthe box opening.

The panels are positioned withinlthecha nnels=141which areprovided atthe top and bottom of the box but do not extend to the corner of the boxlike the panels do in Fig.

1. The corners. each consist of a rounded sheet metal member 15, shownin Flg. 13, havingan inturned flange l6 atthe top and bot- .tom and .apanel f bracket 17 .at each side welded to the member. 15 and adapted tozreceivex-the adjacent panel. The corners of the channel frame areextruded at.18, asshown in Figs. 8 and 11', to receivethe' member 15 andthe flanges 16 and when thus assembled the panels extend, into and areheld by the brackets 17,.as shownin Figs. and

11. In this wayfthe member covers the ends of the panel and at the sametime provides a rounded corner forthe box. In order to secure the boxtogether the top and bottom memberl l .at' each corner is provided withan extruded aperture 19 and the member 15 is 1 provided withanapertureQOin the top and bottom flanges .16 into which the-extrudedmetal about the aperturesu19 extends. An elongated rivet 21 is thenextended through the apertures 19 and in the frame members 1 1 and-thecornermemb'er 15and each end of-the'rivet is upset at 22 to fill theextruded apertures19 flush with the top of the respective frame members.In this way the =box1stied together at the fourcorners very firmlyand'the rivets 21 at the same time are out ofthe way as :they extendthro-ugha space normally occupied in the remainder of panels as will beunderstood from Fig. 9. g

The brackets 17 which engage the ends of the panels are suflicientlyshort so that they do not interfere with fitting the frame members onthe corners, the ends of the brackets :lTterminating short of'thechannel frame members 14 as will be understood from Fig. 10. .Itwillthus be noted thatpthe box in either form is tied together .byonlyfour tension members so that theminimum number of rivets, bolts or othersecuring means is utilized.

From the foregoing description it becomes evident thatthe device is verysimple and eificient in operation,is very strong in construction, may bereadily taken apart or reassembled andprovides a device whichaccomplishesthe'objects described.

, Having thus fully described my invention, its utility and mode ofoperation, what I claim and desire to secure by Letters Patent of theUnited States is 1. A box comprising a pair of continuous frame membersformed of sheet metal and providing a channel and having a flangeextending inwardly of the frame from one edge of the channel, the framesbeing positioned with the open side of the channels facing each other, awood panel member having its opposite edges positioned in the channelsof the respective frames, a bottom member supported on the flange of thelower frame, bolts extending through the flanges of the respective framemembers adapted to hold the same rigidly in assembled relation, andmetal elements extending between the two frames on the exterior of thebox limiting the extent to which the frame members may be drawn togetherby the bolts thereby preventing collapse of the wood panels.

2. A box consisting of a pair of sheet metal rectangular frame membersof channel form in cross section and positioned with the open sides ofthe channel facing each other, a wood panel for each of the four sidesof the box having the opposite edges supported in the respectivechannels, a metal corner member of angle form covering the meeting edgesof the wood panels and extending into the channel of each frame member,a tensioning means for drawing the frame members toward each other toplace the parts under compression strains, the angle members limitingthe extent to which the frames may be drawn together and therebylimiting the pressure to which the panel members may be subjected.

In testimony whereof I sign this specification.
